Abstract
A multilayer fuel pipe comprises an inner layer, a middle layer and an outer layer in sequence from inside to outside, wherein the inner layer is an FKM material layer, the middle layer is a THV material layer, the outer layer is an AEM material layer, and a woven layer is arranged between the middle layer and the outer layer. The utility model discloses an inlayer is the FKM material layer for the fluororubber layer, inlayer and fuel contact, and oil resistance is good, and the middle level is the fluororesin barrier layer, and the skin has good ageing-resistant, ozone resistance's protective layer, has increased the life of burning oil pipe, and outer inboard weaving layer improves the compression resistance of burning oil pipe.
Description
Technical Field
The utility model relates to an automobile oil piping system especially relates to a multilayer fires oil pipe.
Background
The automobile fuel pipe is mainly used for providing a gasoline circulation pipeline, the permeability and the strength of the fuel pipe are improved along with the improvement of the requirements of fuel evaporation emission regulations, the emission limit of automobile exhaust pollutants is stricter along with the coming out of the national six policy and the development of oil-electricity hybrid automobiles, and in order to effectively reduce the evaporation, permeation and emission of pollutants, the evaporation and seepage of fuel from the fuel pipe are required to be reduced, so that the aims of safety, energy conservation and environmental protection are fulfilled.
Disclosure of Invention
The utility model provides a solve above-mentioned problem, provide a multilayer hyposmosis fuel pipe that car was used.
The utility model discloses the technical scheme who takes:
a multilayer fuel pipe comprises an inner layer, a middle layer and an outer layer in sequence from inside to outside, wherein the inner layer is an FKM material layer, the middle layer is a THV material layer, the outer layer is an AEM material layer, and a woven layer is arranged between the middle layer and the outer layer.
The inner layer and the middle layer are provided with a first bonding layer, and the middle layer and the weaving layer are provided with a second bonding layer.
The first bonding layer and the second bonding layer are ECO material layers.
The utility model has the advantages that: the utility model discloses an inlayer is the FKM material layer for the fluororubber layer, inlayer and fuel contact, and oil resistance is good, and the middle level is the fluororesin barrier layer, and the skin has good ageing-resistant, ozone resistance's protective layer, has increased the life of burning oil pipe, and outer inboard weaving layer improves the compression resistance of burning oil pipe.
